Bombardier Inc ended up 15.7 percent at C$2.73 after soaring as much as 26.4 percent following a game-changing deal with Airbus SE.

The overall industrials group rose 0.4 percent.

“It could be a win-win-win scenario. I think time will tell. ... It seems like a very creative way to perhaps get a win out of the scenario,” said Kevin Headland, senior investment strategist at Manulife Investments.
